# overloadable

Easy to use overloadable functions in rust using nightly features.

This crate provides you with the capabilities to overload your functions in a similar style to C# or C++, including support for meta attributes, type parameters and constraints, and visibility modifiers. 

Please visit the documentation for futher information. 

# Note

This is a **nightly** crate. You _must_ include the following line in your code for this crate to compile:

```rust

#![feature(unboxed_closures, fn_traits)]

```

## Example:

```rust

#![feature(unboxed_closures, fn_traits)]

use overloadable::overloadable;

overloadable! {

    pub func as

    #[inline(always)]

    fn(x: usize, y: usize) -> usize {

        x * y

    },

    fn<'a>(x: &'a usize) -> f32 {

        *x as f32

    },

    fn<'a, T>(x: &'a [T]) -> &'a T where T: std::fmt::Debug {

        println!("Found {:?}", &x[0]);

        &x[0]

    }

}

fn foo() {

    assert_eq!(func(2, 3), 6);

    assert_eq!(func(&32), 32.0);

    assert_eq!(func(&[1, 2, 3, 4][..]), &0);

}

```
